Thanks for trying - but - like Mark said, each 3x3 grid has to have the numbers 1-9 as well. Also, it needs to be in some random order - making it more difficult to solve.

Go Hogs! (we'll get 'em next year...)

>>I thought it would be a great project for me to get my feet wet w/Visual Studio...but...I'm having a terrible time trying to figure out the logic to create the puzzles. Here are the requirements:
>>
>>1. There's a 9x9 grid
>>2. Each column contains the number 1-9 without duplicates
>>3. Each row contains the numbers 1-9 without duplicates
>>4. Each 3x3 grid contains the numbers 1-9 without duplicates - there are 9 of these 3x3 grids and they do not overlap - it looks something like this:
>>
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>x x x - x x x - x x x
>>
>>It sounded rather easy at first - but - I can't get a handle on how to do this - any suggestions would be great. All I'm looking for is the logic - so if you only "speak" VFP, that would be fine...

>>Thanks!
